DETACHABLE SPRING-HINGE.

Specification of Letters Patent. Patented May 20, 1919.

Application filed October 6, 1916. Serial No. 124,188.

To all whom it may concern: 7

Be it known that I, GEORGE N. BARGUS, a citizen of the United States, residing at \Vabash, lVabash county, and State of Indiana, have invented and discovered certain new and useful Improvements in Detachable Spring-Hinges, of which the following is a specification.

My invention relates to detachable'spring hinges and its object is to provide an article of this class having means of a simple construction whereby the hinge may be reversed for use on either a right hand or left hand door, and to provide a simple form of holdback spring for the hinge.

With these objects in view my invention is embodied in preferable form in the construction and arrangement hereinafter described and illustrated in the accompanying drawings.

In these drawings Figure 1 is a front view in elevation of the hinge; Fig. 2 a side view; Fig. 3 a rear view with the jamb plate removed; Fig. a a detail perspective of the jamb plate; Fig. 5, a section on the line 5-5 of Fig. 1; and Fig. 6 a similar section showing the hinges open and in hold-back position.

Referring to the drawings 1 indicates a hinge leaf which is adapted to be secured to the door by means of, screws passing through the screw holes 2. The leaf section which is detachably connected to the jamb plate is indicated by 3 and 4: is the jamb plate to which the detachable connection is made. This jamb or attaching plate is provided with screw holes 5 adapted to receive screws which secure the plate to the door jamb. The leaf plate 3 is provided with openings 6 adapted to register with the screw holes 5 and which openings are sufficiently large to permit the heads of the attaching screws which secure the jamb plate to pass through and beyond the plate 3, for the purpose of permitting the screws to be secured after the hinge and jamb plate have been connected, and to permit the hinge to be readily lifted from the jamb plate. To provide for the detachable engagement of the hinge and jamb plate, the leaf section is provided with longitudinal flanges or lips 7 along its large edges which are turned over to provide open retaining grooves, and which flanges are open at both ends. These open end flanges are adapted to slip over the upper ends of the longitudinal guide flanges or rails 8, formedalong the vertical edges whereby the longitudinal flanges of the leaf 7 3 may be readily engaged with these rails, when the door is toi be hung or lifted from the jarnh-plate. Y i

The jamb plateis provided along its bottom 'With'a horizontal ledge 9 constituting a stop and supporting member and against which the outer face of one of the pintle ears 10 of the leaf 3 is adapted to bear when the door is hung whereby the hinge and door are supported.

The hinge is shown as arranged for a hight hand door. To hang the door on the left hand of the jamb, it is merely necessary to secure the jamb plate 4: on such side of the door, and reverse the hinge, whereupon the opposite end of the leaf 3 may be engaged with the rails of the jamb plate, in which disposition of the parts, the ledge 9 will again be at the lower end of the jamb plate and will serve as the supporting means for the hinge and door.

It will thus be seen that the open ended straight retaining grooves of the hinge leaf 3, which are the same at both ends, in cooperation with the straight longitudinal rails of the jamb plate adapted to receive the hinge leaf only at their upper ends, and with the horizontal supporting ledge of the jamb plate, provide a simple form of reversible detachable hinge, and at the same time requires the plate-engaging means to be formed on one hinge leaf only, and avoids the objection of excessive sticking and jamming of the parts sometimes encountered in wedge shaped connecting elements.

The turned over lips along the edges of the leaf are of especial advantage in ena bling the utilization of sheet metal.

Extending through the opposite ears 10 of the door engaging leaf 1 of the hinge to one side of the line of the pintles is a spring 12, having a hinge coil 13 in its center which coil lies parallel to the face of the hinge, and is offset from the longitudinal line of the spring and extends over the edge of the leaf which is attached to the jamb spring pressure on each side of the pivotal line is balanced, the outer edge of the coil will bear against the face of the section 3 and frictionally retain the door in half way position and when the door is swung past the right angle, it will be snapped open and held open, by the force of the spring. This arrangement thus provides a pivoting and frictional spring which will act effectually as an automatic hold back and enable the usual auxiliary constructions such as cams, pins and levers to be dispensed with.

Having thus described my invention what I claim is,

In a detachable spring hinge separable by relative movement of the parts in a vertical plane, in combination with a leaf of sheet metal having its vertical longitudinal edges turned inwardly to provide straight parallel groove-forming retaining lips, the grooves being open at both ends, an attaching amb plate having straight parallel vertical formations to engage said grooves, and having at its lower end an outwardly turned flange constituting a supporting and stop member for the hinge, and means for securing said j amb plate to a jainb, said leaf having an opening whereby said securing means may be removed or secured while the leaf is in position.

In witness whereof, I have hereunto set my hand and seal at Wabash, Indiana, this 16th day of September, A. D. nineteen hundred and sixteen.
